Technical Field

The present invention relates to a brine supply structure of a chlorine disinfectant fluid generator, and more particularly, to a chlorine disinfectant fluid generator, which is equipped with a saturated salt trap part and a dilution water supply part in a partitioned space on one side from a dissolution tank, wherein the saturated salt trap part is formed in a lower part in a manner of being connected to a bottom part of the dissolution tank, and the dilution water supply part is formed in a partitioned manner in an upper part of the saturated salt trap part, thereby making the device smaller and lighter.

Background

Generally, Sodium Hypochlorite (NaOCl, Sodium Hypochlorite) is a chlorine disinfectant in the form of a colorless and transparent liquid having a strong chlorine odor, which is used as a sterilizing apparatus in water purification plants and sewage treatment plants, a cooling water boiler in general chemical plants, desalination process treatment water, cooling water treatment in power plants, drinking water treatment, plant and vegetable processing, meat processing, washing in swimming pools, paper making, and household bleaching agent.

In a non-diaphragm sodium hypochlorite generator used for producing such sodium hypochlorite, a large amount of salt is precipitated in a predetermined amount of introduced water and water under pressure and held for 8 to 24 hours, and thus a predetermined amount of saturated saline water under pressure, in which 28 to 30% of the salt is dissolved and saturated, is mixed by a pump or the like, and the salt in the diluted saline water is electrolyzed by a direct current voltage applied to both sides of an electrode while passing the diluted saline water having a salinity of 2.8 to 3.0% through an electrolytic cell having a series of electrodes (anode and cathode) without a diaphragm (ion exchange membrane).

That is, 2.8 to 3.0% of the dilute brine flowing into the electrolyzer is decomposed into Sodium ions (Sodium ion. na +) and Chloride ions (Chloride, Cl-), the Chloride ions are oxidized at the anode to become chlorine (formula 1), the Sodium ions are reduced at the cathode to produce Sodium (formula 2), the produced Sodium reacts with water to become Sodium hydroxide (NaOH, caustic soda) and hydrogen (formula 3), and then the chlorine produced at the anode reacts with the Sodium hydroxide to produce Sodium hypochlorite (NaCl) (formula 4).

Na + + e- → Na- - - - - - - - - - - - (formula 2)

NaOH + Cl2 → NaOCl + HCl- - - - - - - - - - - - - - - (formula 4)

The sodium hypochlorite thus produced is used as a chlorine disinfectant or an oxidizing agent in a safe form as brine at a site where disinfection or oxidation is required, and the production amount and the concentration of the sodium hypochlorite are determined by the diluted brine in which the supplied introduced water and the brine are mixed according to faraday's law.

Fig. 1 schematically shows the constitution of a sodium hypochlorite generating apparatus according to the prior art. As shown in fig. 1, such a sodium hypochlorite generating apparatus includes a brine storage tank 10 for precipitating salt in water and an electrolytic bath 20 having a series of electrodes (anode, cathode), and is configured such that a brine supply pipe 11 for supplying brine to the electrolytic bath 20 is connected between the brine storage tank 10 and the electrolytic bath 20.

Further, an introduced water supply pipe 12 for supplying introduced water is connected to one side of the brine supply pipe 11 in a communicating manner, and plays a role of diluting and supplying a certain portion of the brine in the brine storage tank 10 when it moves toward the electrolytic bath 20. A flow meter 14 and a flow rate control valve (not shown) are installed in the brine supply pipe 11 and the introduced water supply pipe 12.

The sodium hypochlorite generating apparatus configured as described above supplies brine from the brine storage tank 10 through the brine supply pipe 11, and if the introduced water is supplied through the introduced water supply pipe 12, a certain portion of the brine is diluted by the introduced water, and the diluted brine (brine 1: introduced water 10) moves to the electrolytic bath 20.

At this time, in the process of passing through the electrolytic cell 20 having a series of electrodes (anode, cathode), the diluted brine is electrically decomposed and recombined by the direct current voltage distributed to both sides of the electrodes, and is converted into sodium hypochlorite of an appropriate effective brine concentration, and the sodium hypochlorite is discharged through the sodium hypochlorite discharge pipe 13 connected to the upper end side of the electrolytic cell and stored in a certain place.

When sodium hypochlorite stored in a certain place is used, it is mixed with a certain proportion of water according to the required chlorine amount of the place where the sodium hypochlorite is used.

However, the sodium hypochlorite generator having such a structure employs the following means: in a pipe branching from a waterway plug or a pipe in which a conventional water pressure is formed and leading into an electrolytic cell, an electric on-off valve, a pressure reducing valve, or a flow regulating valve is provided to adjust the flow rate and pressure of the lead-in water, and at this time, if the pressure in the pipe fluctuates, the flow rate and pressure of the lead-in water flowing into the electrolytic cell also fluctuate, so that the concentration and production amount of sodium hypochlorite generated from the electrolytic cell are different, and the water amount is suddenly reduced, and the electrolytic device is heated and damaged due to overheating, and further, if the electrolytic device is powered off during operation, the electric on-off valve which is opened is not closed, and the lead-in water is continuously supplied to the electrolytic device which is not in operation, and therefore the concentration of sodium hypochlorite generated and stored in the storage tank is reduced, or the lead-in water to overflow the storage tank.

Further, since a flow rate control valve and a solenoid-shaped electric valve provided between an outlet of the intake water supply pump and a pipe at a place where the disinfectant is used are provided in series one by one in order to obtain a desired concentration of chlorine disinfectant by diluting a predetermined amount of intake water in sodium hypochlorite discharged from the electrolytic bath, it is inconvenient to adjust the flow rate control valve one by one in accordance with the purpose of use of the disinfectant.

Further, there are problems in that a sodium hypochlorite discharge port of the electrolytic cell is connected to another sodium hypochlorite storage tank, a pump for supplying sodium hypochlorite is additionally provided between the sodium hypochlorite storage tank and a pipe where the disinfectant is used, so that there is inconvenience in that the supply amount of sodium hypochlorite needs to be adjusted in accordance with the introduction amount and pressure of the introduced water, and production costs of products are increased due to the additional provision of the sodium hypochlorite storage tank and the pump.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a schematic configuration diagram of a chlorine disinfectant fluid generator according to the present invention.

Referring to fig. 2, disclosed is a chlorine disinfectant fluid generator in which a brine supply unit 200, a hypochlorous generator 300, and a control unit 500 are disposed in a single body case 100, the brine supply unit 200 mixes intake water at a certain ratio in a piping line for supplying saturated brine to generate dilute brine, the hypochlorous generator 300 receives the supply of the dilute brine to generate sodium hypochlorite through an electrolysis process, and mixes the intake water with the sodium hypochlorite at a desired ratio to generate chlorine disinfectant fluid, and the control unit 500 controls the brine supply unit 200 and the hypochlorous generator 300.

The brine supply unit 200 is provided with a dissolution tank 220, a saturated salt trap 225 and a dilution water supply unit 230 are disposed in a space on one side partitioned from the dissolution tank 220, the saturated salt trap 225 is formed at a lower portion so as to be connected to a bottom of the dissolution tank 220, and the dilution water supply unit 230 is formed at an upper portion of the saturated salt trap 225 so as to be partitioned.

The brine supply unit 200 is constructed such that the dissolution tank 220, the saturated salt trap 225, and the dilution water supply unit 230 are integrally provided in one tank, and thus, if the dissolution tank 220, the saturated salt trap 225, and the dilution water supply unit 230 are integrally formed in an integral tank, there are advantages in that the apparatus can be made smaller and lighter, and the manufacturing cost can be saved by simplifying the manufacturing process and the assembly process.

Further, there is an advantage in that management or conveyance of the apparatus becomes easy by miniaturization of the apparatus.

An intake water injection nozzle 221 for injecting intake water is formed at the upper part of the dissolving tank 220. At this time, the nozzle direction of the intake water spray nozzle 221 is directed toward the upper inner wall surface of the dissolution tank 220, and the intake water is sprayed on the upper inner wall surface of the dissolution tank 220 and flows down along the wall surface.

Further, it is preferable that the injection angle of the introduction water injection nozzle 221 is large so as to uniformly inject the wall surface in 4 directions.

Referring to fig. 2, the introduced water injection nozzle 221 is illustrated as being provided to inject water from the left side wall surface toward the right side wall surface, but is not limited thereto, and may be formed to inject water at a wide angle in such a manner that the introduced water injected from the upper center hits the front, rear, left, and right sides of the dissolution tank 220, or may be formed as a 4-direction injection nozzle.

The present invention prevents the salt crystals from adhering to the wall surface of the dissolution tank while the intake water is supplied from the intake water injection nozzle 221.

This is advantageous in that the concentration of the brine in the dissolving tank 220 can be uniformly adjusted, thereby maintaining a constant quality of the sterilized water finally produced.

In addition, the present invention prevents the salt from being fixed on the wall surface of the dissolution tank 220, and thus there is also an advantageous aspect in maintenance. For example, it is possible to prevent the salt from being scattered inside the apparatus or the internal parts due to the phenomenon that the salt crystals overflow into the dissolution tank 220, thereby causing various troubles, corrosion, and the like.

At this time, in the dissolving tank 220, the salt is dissolved in a certain amount of water, thereby generating saturated salt having a concentration of 28-30%.

A filter 223 may be formed at the inlet of the saturated salt trap part 225 at the bottom of the dissolution tank 220.

For example, the brine dissolved in the dissolution tank 220 moves to the saturated salt trap 225, and a filter 223 is provided on the moving path to filter foreign substances.

A brine level switch 227 is formed in the saturated salt trap 225.

At this time, the brine level switch 227 is provided above the saturated salt trap 225, and controls the supply of the intake water by sensing the decrease of the saturated brine level to a certain level or less.

The brine level switch 227 may be operated in a floating manner, in which case salt crystals may be attached to the swirling portion without being operated. Accordingly, in the present invention, in order to cope with this situation, a cleaning water spray nozzle 229 for removing salt may be formed at the brine level switch 227.

Preferably, the cleaning water spray nozzle 229 intermittently or periodically sprays water to remove salt crystals fixed to the salt water level switch 227, while controlling the amount of the sprayed water to such an extent that the concentration of the whole saturated salt, i.e., the quality of the finally generated sterilizing water, is not affected.

At this time, the saturated brine in the saturated salt trap 225 is transferred to the hypochlorous acid generator 300 by the first pump 240.

A dilution water level switch 231 may be similarly formed in the dilution water supply unit 230 provided above the saturated salt trap 225, and the supply of the intake water may be controlled by sensing the decrease in the water level below a certain level.

At this time, the dilution water in the dilution water supply unit 230 is transferred to the hypochlorous acid generation unit 300 by the second pump 250.

The saturated brine transferred by the first pump 240 and the diluted brine transferred by the second pump 250 are supplied to the hypochlorous generating unit 300 while being merged into one line, and the transfer amounts of the first pump 240 and the second pump 250 are controlled so that the brine diluted at a ratio of 2.8 to 3.0% is supplied to the hypochlorous generating unit 300.

Further, the pipe line connected from the brine supply unit 200 to the hypochlorous acid generation unit 300 is provided so as to be directly connected inside the tank 100, but the flow splitting unit 210 may be provided so as to lead a part of the pipe line from the outside of the tank 100, so that the pipe line exposed to the outside of the tank 100 can be arbitrarily connected or cut.

The flow divider 210 serves as a pipe for supplying diluted saline water when the sterilized water generating apparatus is used, and serves as a drain passage for separating the pipe and discharging saline water in the saline water supply unit to the outside when the sterilized water generating apparatus is not used for a long time after the sterilized water generating apparatus is used.

FIG. 3 is an exploded perspective view showing the hypochlorous acid generating part of FIG. 2, and the hypochlorous acid generating part 300 will be described with reference to FIG. 3.

The hypochlorous acid generating unit 300 includes an electrolytic cell for generating sodium hypochlorite (hereinafter, referred to as hypochlorous acid) by receiving a supply of the dilute brine and performing electrolysis.

The hypochlorous acid generating part 300 is provided with a partition wall 303 in the middle, the first body 301 and the second body 302 are coupled to each other in a face-to-face manner, the first body 301 and the second body 302 have their facing inner surfaces depressed to define a plurality of separation spaces, and the respective spaces are communicated with each other through a flow path formed at a predetermined position of the partition wall 303 to form a moving path in each stage.

The first body 301 holds a space portion between the cooling tank 310 and the hydrogen separation tank 330 by trapping one side surface of the synthetic resin plate material having a predetermined thickness in an inward direction.

The cooling tank 310 is a place to receive the introduced water directly supplied from the outside through a water line, and is divided at a lower side of the first body 301.

A raw water inlet 301a connected to an external intake line is formed in a lower wall surface of the cooling tank 310, and the raw water inlet 301a is preferably located at a lower center position of the cooling tank 310.

A drain 301b for discharging water in the cooling tank 310 to the outside is formed at the bottom of the cooling tank 310.

At this time, the inflow water supplied through the raw water inlet 301a moves to a point above the cooling tank 310 and moves to the dilution tank 340 side, and a second flow path 303b connecting both sides is formed in the partition wall 303 provided between the cooling tank 310 and the dilution tank 340.

At this time, the plate-shaped water pressure dispersing rib 301c is formed above the raw water inlet 301a, so that the phenomenon that the pressure is concentrated due to the strong water pressure of the inflow water supplied through the water line colliding with the water pressure dispersing rib 301c can be prevented.

A hydrogen separation tank 330 is formed above the cooling tank 310.

The hydrogen separation tank 330 is formed to be composed of a vertical section and a horizontal sectionIn the shape, the lower part of the vertical section is formed at a position facing the electrolytic cell 320 side of the second body 302 side, and the horizontal section is formed at a position facing the dilution tank 340 side of the second body 302 side.

In this case, the cooling tank 310 defined below the hydrogen separation tank 330 is formed with the hydrogen separation tank 330The boundary surface corresponding to the curved shape has a discharge portion 301d extending to a position equivalent to the height of the horizontal section toward the horizontal section of the hydrogen separation tank 330. At this time, it is preferable that the shape of the discharge portion 301d has a funnel shape gradually narrowing toward the upper portion, guiding the discharge of the inflow water to gather toward one place.

The second body 302 is configured to secure a space between the electrolytic bath 320 and the dilution tank 340 by inwardly sinking one side of the synthetic resin plate having a predetermined thickness.

The electrolytic bath 320 is a space for receiving the saturated brine supplied from the brine supply unit 200 and performing electrolysis, and is provided with a plurality of electrode plates (not shown) for electrolysis, forming a space of an approximately rectangular box shape.

A brine inlet 302a for receiving the diluted brine supplied from the brine supply unit 200 is formed at a lower portion of the electrolytic cell 320, and a hypochlorous acid outlet 302c for discharging the brine therein to the outside is formed at a bottom portion thereof.

In this case, the electrolytic cell 320 has an entire area corresponding to the cooling bath 310 with the partition wall 303 provided in the middle, and a part of the upper space overlaps with the vertical section of the hydrogen separation bath 330, and the partition wall 303 at the portion overlapping with the vertical section is drilled to form the first flow path 303a for moving the electrolyzed hypochlorous gas to the hydrogen separation bath 330.

The general structure of the electrolytic cell 320 will be described, in which electrode plates of the anode and the cathode are arranged alternately with a certain interval in the internal space of the frame having the shape of "ロ", and 2.8 to 3% of the dilute brine is supplied through the brine inlet provided at one side thereof, and is electrolyzed to generate hypochlorous acid.

The generated hypochlorous acid moves to the hydrogen separation tank 330, and hydrogen gas (H2) generated in the electrolysis is separated from the hydrogen separation tank 330 and discharged.

At this time, the hydrogen gas (H2) having a small specific gravity is accumulated to the upper part of the hydrogen separation tank 330, and the upper end of the horizontal section of the hydrogen separation tank 330 is formed to be inclined, so that the hydrogen gas can be guided to be accumulated to the upper side of the inclined surface regardless of the movement of the hypochlorous acid.

In the present invention, a gas discharge part may be additionally formed to form the upper end of the horizontal section of the hydrogen separation tank 330 in a form gradually inclined downward from the section communicating with the side of the electrolytic tank 320 to the side of the section communicating with the side of the dilution tank 340, so that the hydrogen gas may be guided to be accumulated at the end of the vertical section of the hydrogen separation tank 330 and discharged to the outside.

In addition, a dilution tank 340 is formed in the upper portion of the electrolytic tank 320, and mixes sodium hypochlorite (hypochlorous acid) that has passed through the electrolytic tank 320 and the hydrogen separation tank 330 with the intake water to generate chlorine disinfectant water in a desired ratio.

The dilution tank 340 is formed with a rectangular box-shaped space extending in the longitudinal direction from the upper part of the electrolytic bath 320.

At this time, a hypochlorous acid discharge port 302c is formed at one side of the dilution tank 340, and hypochlorous acid diluted by mixing with introduced water is finally discharged.

At this time, the one end portion region of the entire area of the dilution tank 340 overlaps the discharge portion 301d of the cooling tank 310 and the horizontal section end portion of the hydrogen separation tank 330, and a second flow path 303b for allowing the hypochlorous gas to flow into the dilution tank 340 is formed by drilling a hole in the partition wall 303 at a portion overlapping the horizontal section end portion of the hydrogen separation tank 330, and a third flow path 303c for allowing the cooling water to flow into the dilution tank 340 is formed by drilling a hole in the partition wall 303 at a portion overlapping the discharge portion 301d of the cooling tank 310.

At this time, as the second flow path 303b and the third flow path 303c are formed in adjacent positions, there is a possibility that a problem of backflow of the introduced water toward the hydrogen separation tank 330 for supplying hypochlorous acid may occur due to a pressure difference of the introduced water flowing into the dilution tank 340, and in order to prevent this problem, an elbow 303d is provided on the third flow path 303c side for supplying hypochlorous acid, and a discharge side end portion of the elbow faces the hypochlorous acid discharge port 302c side, so that backflow of the inflow water flowing in through the second flow path 303b can be prevented.

At this time, a reverse flow prevention damper 303e may be further provided, which extends to the discharge side end portion of the elbow 303d, and the reverse flow prevention damper 303e functions as a check valve that fundamentally blocks the inflow water (raw water) from flowing into the hydrogen separation tank 330.

The backflow prevention damper 303e prevents the fluid from moving backward due to the pressure formed in the pipeline after the use of the sterilizing water generator, and functions as a pressure control device that smoothly restarts the operation when the device is reused.

To explain the operation of the hypochlorous acid generating part 300 according to the present invention, brine is first supplied from the brine supply part 200 side to the electrolytic bath 320. The brine undergoing the electrolysis process in the electrolytic cell 320 then produces sodium hypochlorite (hypochlorous acid) with an effective brine concentration of 3100-.

Such high-concentration hypochlorous gas is separated from the hydrogen gas by the hydrogen separation tank 330, and only pure hypochlorous gas is supplied to the dilution tank 340.

At this time, the hypochlorous acid having passed through the hydrogen separation tank 330 and the inflow water having flowed in through the cooling tank 310 are mixed in the dilution tank 340 and diluted to an appropriate concentration, and then used as chlorine disinfectant.

The dilution tank 340 can generate chlorine disinfectant water having various concentrations according to the flow rate of the introduced water and the flow rate of the hypochlorous acid.

For example, high-concentration chlorine disinfectant water diluted to a concentration of 100ppm for cleaning or disinfecting hands, wiping cloths, chopping boards, and the like, medium-concentration chlorine disinfectant water diluted to a concentration of 50ppm for cleaning meat or fresh products, and low-concentration chlorine disinfectant water diluted to a concentration of 30ppm for cleaning vegetables or fruits can be generated.

A temperature sensor T is provided at an inlet of the intake water to be supplied to the brine supply unit 200.

The temperature sensor T measures the temperature of the introduced water and notifies the measured value to the central processor 510, and the central processor 510 judges the measured value of the temperature sensor, judges that there is a danger of freeze-damage in the case below the set value, and gives a warning alarm to the user.

The illustration of the reminder device is omitted with reference to the drawings.

The invention makes the user recognize the danger of freezing and deal with the danger in advance, thereby preventing the problem that the device can not be used in winter.

The cpu 510 determines the value of the temperature sensor T, and controls the supply current to the electrolytic cell by the current controller 520 so that the electrolysis temperature of the hypochlorous acid generator 300 is always kept at a reference value.

For example, it is possible to prevent the occurrence of problems such as a power supply device failure due to overcurrent supply in the electrolytic cell caused by seasonal changes in the temperature of the intake water and a rise in the temperature of the intake water due to global warming.

The present invention maintains a constant reaction temperature and a constant amount of electrolytic current in the electrolytic cell, thereby maintaining a constant concentration of sterilizing water and producing sterilizing water of average quality.

Fig. 4 is a schematic configuration diagram of a chlorine disinfectant fluid generator according to another embodiment of the present invention, and referring to fig. 4, the saline water supply unit 200 is separately formed in a separate case and then connected to the apparatus body by a connection device 600 including a cable 610 and a hose 620.

As described above, the present invention has an effect of stably supplying high-quality brine to an electrolytic cell by the brine supply unit, thereby improving electrolysis efficiency.

In addition, the present invention has an effect that a large amount of saturated salt can be supplied more stably by providing an additional saturated salt trap in the brine supply part, thereby increasing the working time and working capacity of the sterilized water.
